What happens in “Known Unknowns”

After a wild night out, a teenage girl is brought to Princeton Plainsborough with severely swollen appendages. The team must work to diagnose the young girl, who is less than honest about what happened the night she fell ill. As her condition worsens, she becomes unable to distinguish fact from fiction. Meanwhile, Cuddy, Wilson and House spend a weekend away from the hospital to attend a medical conference, but things don’t go as planned when House’s private investigator, Lucas returns.
